Creating virtual environment using conda and other useful commands
In Anaconda Prompt, you can create a virtual environment with a specific Python version using the conda create --name django-app python=3.8 command. This command will create a new virtual environment named django-app with Python version 3.8. You can change 3.8 to any other desired Python version. After running the command, you will be prompted to proceed. Type y to confirm and proceed with the installation.Keep on reading to learn other useful commands.
Checking list of virtual environments
You can check list of environments in conda using the command conda env list:
(base) C:\Users\codingissimple>conda env list
# conda environments:
#
base * C:\Users\codingissimple\anaconda3
django-app C:\Users\codingissimple\anaconda3\envs\django-app
flask-app C:\Users\codingissimple\anaconda3\envs\flask-appActivating virtual environment
Once the virtual environment is created, you can activate it using conda activate django-app command. Replace django-app with the name of your virtual environment.
Once you activate the newly created virtual environment, you can check the python version by using the command python --version
Deactivating virtual environment
To deactivate the virtual environment and return to the base Anaconda environment, you can run the command conda deactivate
Deleting virtual environment
To remove new environment created and also all of its associated packages you can run conda env remove --name django-app command replace django-app with your virtual environment name.
(base) C:\Users\codingissimple>conda activate django-app
(django-app) C:\Users\codingissimple>python --version
Python 3.8.18
(django-app) C:\Users\codingissimple>conda deactivate
(base) C:\Users\codingissimple>conda env remove --name django-app
Remove all packages in environment C:\Users\codingissimple\anaconda3\envs\django-app:
(base) C:\Users\codingissimple>conda env list
# conda environments:
#
base * C:\Users\codingissimple\anaconda3
flask-app C:\Users\codingissimple\anaconda3\envs\flask-app
(base) C:\Users\codingissimple>conda –help command will give you list of commands you can run.
Let’s create the django-app virtual environment again with python version 3.8 using the command conda create --name django-app python=3.8 , activate it by running the command conda activate django-app and install few packages in this virtual environment.
Installing python packages in virtual environment
Install django and psycopg2 packages in django-app virtual environment
conda install django
conda install psycopg2Seeing list of packages in virtual environment
conda list will give list of packages in environment
(django-app) C:\Users\codingissimple>conda list

zlib 1.2.13 h8cc25b3_0you can also use pip command in conda virtual environment, to install list of packages mentioned in requirements.txt you can run the command pip install -r requirements.txt or to install packages individually you can run pip install django
Installing multiple packages at once
You can also install multiple packages at once
conda install django-crispy-forms django-allauth djangorestframework python-dotenv django-cors-headers django-debug-toolbar django-extensions django-redis-cache django-celery django-guardian django-haystack django-storagesThese are Python packages often used in a Django project to add various functionality to the web application.
Uninstalling packages
If you need to uninstall django or any other package, you can use conda remove package-name or pip uninstall package-name, replace package-name with the name of the package you want to uninstall , to update all the packages you can run conda update --all
Activating virtual environment in vs code editor
To select this newly created django-app virtual environment for your django project in vs code first make sure you have installed python extension for your django project.
Open your project folder in vs code, next open the bash terminal and run the following commands
codingissimple@LAPTOP ~/Desktop/my-django-app
$ which python
/c/Users/codingissimple/AppData/Local/Programs/Python/Python311/python
codingissimple@LAPTOP ~/Desktop/my-django-app
$ conda activate django-app
bash: conda: command not foundAs you can see, you can’t activate the conda created virtual environment using the command conda activate django-app . Close the bash terminal and press ctrl+shift+p shortcut key then pop up will appear search Python: Select Interpreter in it and click on it once found.
Now, you will see list of virtual environments choose the one you want , in this case we will choose django-app virtual environment. If you open new terminal now you will see the virtual environment gets activated. As we have changed the interpreter to choose django-app virtual environment, conda related commands should also work.
You can directly activate the virtual environment by first opening a terminal in vs code then run the command source C:/Users/codingissimple/anaconda3/Scripts/activate django-app , replace codingissimple with the windows username and django-app with virtual environment name. I’m assuming default location of installation of anaconda is the same for you.
codingissimple@LAPTOP ~/Desktop/my-django-app
$ source C:/Users/codingissimple/anaconda3/Scripts/activate django-app
(django-app)
codingissimple@LAPTOP ~/Desktop/my-django-app
$ which python
/c/Users/codingissimple/anaconda3/envs/django-app/python
I hope this article has helped you in creating virtual environment using anaconda prompt , activating it for your python project in vs code.
